i The object of the invention is to provide several improvements inWriting instruments, and particularly in that class quite generallyVreferred toas fountain-pens.

Another object is vto provide a positive means for filling'the reservoirof the foun- Ytain-'pen with aliquid, Which'liquid though comprisinglWater in the present instance may be the usual vliquid ink of oth-ertypes of fountain-pens to which this feature of the invention may beapplied, said iillingineans making it possible With `a most direct man-:ual operation to expel a maximum quanti-tyy of the air from within thereservoir, and consequentlyupon being released insures the reservoirbeing filled `to 4a maximum degree with but a single operation, andautomatically resets the filling means.vr

A further object is to provide an improved feed which too canbe used inmany types of fountain-pens, but which is particularly adaptable for usein the one hereinafter described, said feed comprisingA an ingeniously'present invention comprises additional novel designed channel throughWhich air is permitted to flow With a Vmaximum degree of freedom` pastthe pen-point and into the reservoir, in order that an uninterruptedflow of Water, ork liquid ink, as the case may be, can flow steadilyfrom the reservoir, past the iniiowing air, and to the pen-point, as theopera-tion of Writing with the pen proceeds. l y

Still another object is to provide broadly lfor the manufacture ofliquid inlr in a fountain-pen adjacentV to or in the immediateneighborhood of the pen-point, the reservoir ofthe pen in such casebeing supplied With Water, While entirely outsideV of the reservoir andin fact close to the pen-poiiit or nib there is positioned a soluble inkpellet, past and in Contact With Which the Water from the reservoir Howsand there makes the ink, which isv discharged by and from the pen-point,said pellet being so mounted that When dissolvedva renewing pellet maybe most easily inserted in its stead.

Again, another obl'ect is to provide in such a. feed member, which whenin normal Writ-ing position has a transversely extending aperture, arecess in the undersideA of said member spaced away from said aperture,and a dual holder normally containing ink-making pellets, one portionofA said holder extending into and positioning a reserve pellety in'said recess, and another por serial no'. 35,104. inviami and'nnsappncation ined october a, Serial No. 60,221. 4

tion of said holder extending into and posiy' tioning an active pellet`in said aperture and exposed to Water as it flows from the reservoirpast the feed member to the pen, the Water upon contacting With. saidpellet dissolving the same gradually and causing fluid ink to be made innear proximity to thepen or nib.

And a still further object is to provide as apart of a fountain-pen a.ynovel eraser forVA removing inli marks fromjwriting paper or other usualtypes of Writing material, said eraser comprising an abrasive stonefWhich throughout the'following specifications and claimsis intended toreferto those materia-ls suoli .as ein-ery, carboriindum lstone,

puinice, and the like, which in suitable' shapes are marketedassharpening stones for metal tools," than which they are` much harder,and which Vmaterials are non-Wear-l ing as compared with paper and thelike, such as isvused for Writing purposes.

With these and otherobjects in view, vthe Vtransverse section of thesaine on the line 5-5 of Fig. 4; Fig. 6 is a bottom plan view of thesoluble ink pellet-containing member; Fig. 7 is a side elevation of thesame; and Fig.Y 8 is a side elevation of the feed member; and Fig. 9 isa plan view of the feed member.

Referring to the drawings, the body portion of the fountain-pencomprises an annular Wall 1, surrounding a reservoir section 2, which isclosed at one end 3, and at the other end 4: is externally threaded -toreceive the correspondingly threaded portion 5 of an annular cap 6, Whenthe pen is not in use, the Walls of said capbeingprovided with air'passage-Ways 7, and the interior of said cap terminating in onedirection in the transversely eatending Wall 8, beyond which recess 44,may be positioned in said aperture, the empty cup being then positionedwithin the recess. In the operation of this device, the pelletcontainingmember is provided with vthe. soluble ink-pellets from the magazine 9,and said Vpellets are operatively positioned as shown in Fig. 4 andtogether with the feedmember are in the respective operative positionsshown in'Fig. 2, the cap 6, however, being removed by unscrewing thethreaded portion 5 from the threads 4, and thereafter placing the ,capupon the opposite closed end portion of the body portion of the device.

The head 3l is then manually withdrawn as far as possible untilsubstantially the total length of the bag 2O is compressed against theupper portion of the` wall l (as viewed in Fig. 2), after which thelower portion 22 of the member 16 is immersed preferably in water or anyothersuitable solvent for the ink-pellets, the head 3l then beingreleased and the resiliency of the walls of the bag Q0 withdrawing thestud 26 and operating member 29 into their innermost positions as shownin Figs. 2 and 3, while in so doing the bag has automatically filleditselfrwith the solve-nt. n

The pen is then withdrawn from beneath the surface of the solvent and isthereafter ready for use in the manner intended, namely, as a writinginstrument, for as the pen-point 38 is brought into contact with thewriting material and is either manually or otherwise drawn across saidmaterial, the solvent by capillary attraction is drawn solely from thereservoir 2O through the throat 17, saw-cut 37, channel 40, and past thesoluble inlopellet in the aperture 43, and thence to the pen-point,where it is discharged upon the writing material in accordance with themanipulations of the pen in writing or otherwise.

In practise, it has been found that it re-V quires approximately twofillings of the reservoir with the desired solvent, in order to dissolvecompletely the pellet that is operat-ively positioned 1nv said aperture.Vheni this is done, however, the pellet-containing unit is reversed inposition as hereinbefore described and a second pellet is brought intoposition from the recess 44 in theV aperture 43` and the pen is againready for use, and will continue to be as long as any of the lsolventremains in the reservoir and its throat and a portion of the solubleink-pellets remains in the aperture 43. Obviously, when both pelletshave been dissolved, new pellets may be removed from the magazine 9 andplaced in said holder for further use of the pen.

It is to be understood that the improved filling mechanism for thereservoir 20 in its broadest sense may be comprised within afountain-pen not provided with soluble ink# pellets but which dependsupon liquid inlrv being drawn directly into thereservoir in distinctionfrom the present instance in which only water enters the reservoir, andthe ink is manufactured in the immediate vicinity of the point ofdischarge from the pen-point and as the ink is used.

Furthermore, vthe feed-member hereinbefore described has ybeen sodesigned as to permit a steady inward and outward flow of fluid so as toprovide a positive supply of ink for the pen and thus eliminating theusual interruptions due to Huid from the reservoir failing to iowbyreason of the fact that air is unable to pass inwardly through thefeedmember and into the reservoir. Still again, t-he magazineconstruction and improved eraser stone above described is adapted foruse with many typesof writing instruments and not alone with thathereindescribed.

Having thus described my invention, what I claim and desire to protectby Letters Patent of the United States is:-

3. In a fountain-pen, the combination of a barrel having a throat, afeed-bar removably supported by said barrel in said throat and providedwith a transversely extending aperture opening in one direction adjacentto the underside of the pen, a removable holder adaptedIto contain anink-pellet and normally positioned in said aperture, said pelletbeinggexposed to a solvent flowing past said aperture before beingdischarged as liquid ink by the pen.
